Voice-Enabled AI Agents: The Future of Customer Engagement with Azure AI Speech
Voice interaction is quickly becoming the go-to method for engaging with AI agents. Microsoft’s Azure AI Speech is leading this transformation, powering natural, real-time conversations across industries. From sports teams like the Indiana Pacers to global giants like Coca-Cola, enterprises are embracing voice-enabled AI to elevate customer experiences.
What’s New: Introducing the Voice Live API
Microsoft just launched the Voice Live API in public preview, designed to simplify building voice agents. This unified API supports low-latency, speech-to-speech conversations using your choice of generative AI models. It supports over 150 locales and offers more than 600 realistic voices, including 30+ ultra-natural neural HD voices optimized for chat.
Customization is a big win here. You can fine-tune voices and even add avatars to give your voice agents a unique personality. Plus, advanced audio features like noise suppression and interruption detection ensure smooth, natural conversations.
“The Voice Live API empowers users with streaming interactions supported by their chosen generative AI models.”
Major Updates: Video Translation & Neural HD Voices
Azure AI Speech also rolled out the Video Translation Service with general availability. This service translates videos into 70+ languages while syncing lip movements and preserving emotional tone. The result? Multilingual videos that feel authentic and immersive.
Additionally, the DragonHD Neural TTS voices are now generally available. These voices use large language models to capture emotional nuances and context, making AI conversations sound incredibly natural. Custom voice fine-tuning is supported, allowing brands to create voices that truly represent them.
“Azure AI Speech DragonHD TTS voices incorporate advanced features to identify emotional cues within the input text.”
Why It Matters: Real-World Applications and Expanded Language Support
Companies like CommerzBank, the Government of Malta, and Anker are already integrating these voice capabilities into customer service, wearable devices, and call centers. The Voice Live API’s compatibility with Azure Communication Services makes it easy to embed voice AI into existing telephony systems.
Moreover, Fast Transcription has expanded its language support to include Danish, Finnish, Hebrew, Indonesian, Polish, Portuguese, Swedish, and more. This makes transcription and multilingual support more accessible for global businesses.
